Service handover method and apparatus

Abstract

A service handover method includes receiving a handover request signaling sent by a multi-card user equipment. The handover request signaling is configured to request a handover to a second communication system, the handover request signaling carries second service information, and the second service information is service information of a to-be-transmitted service of the multi-card user equipment in the second communication system. The method further includes generating a handover response signaling in response to determining to allow the multi-card user equipment to perform a handover operation based on first service information and the second service information. The handover response signaling carries handover configuration information, and the first service information is service information corresponding to the to-be-transmitted service of the multi-card user equipment in the first communication system.
